Public Functions

iterator begin() const noexcept

sentinel end() const noexcept

bool serialize_turtle(writer::BufWriterParts writer) const noexcept

Serialize this graph as Turtle This function will internally create a SerializationState and call begin and flush on it when appropriate.

Parameters:

writer – writer parts

Returns:

true if serialization was successful, false if a call to W::flush was not able to make room

Graph anonymize(util::Anonymizer &anonymizer) const

Anonymize the graph by removing all information except for the graph structure itself.

See rdf4cpp::util::Anonymizer for details

Public Members

template<typename ErrF = decltype([](parser::ParsingError) noexcept {})> void load_rdf_data(std::istream &rdf_file, parser::ParsingFlags flags=parser::ParsingFlags::none(), parser::ParsingState *state=nullptr, ErrF &&errf={}) requires std bool serialize_turtle (writer::SerializationState &state, writer::BufWriterParts writer) const noexcept

Serialize this graph as N-Triples.

Param writer:

writer parts

Param writer:

writer parts

Return:

true if serialization was successful, false if a call to W::flush was not able to make room Serialize this graph as Turtle This function does not call begin or flush on the given state, it just serialized the contents of this Graph using it.

Return:

true if serialization was successful, false if a call to W::flush was not able to make room
